# Data Push ### Data Push: Threshold-Based Data Updates APRO Data Push offers a **"Push-Based"** data model, which we use to provide [**Price Feed**](https://docs.apro.com/en/data-push/price-feed-contract) services. In this model, decentralized independent node operators continuously aggregate and push data updates to the blockchain when specific price thresholds or heartbeat intervals are reached. This approach enhances blockchain scalability, supports a broader range of data products, and ensures timely updates. ### Trusted Data for DeFi APRO Data **Push** **Model** is widely utilized in various applications, especially in DeFi protocols and smart contracts, providing highly trusted, real-time, and secure data. It is also critical for emerging markets like Bitcoin Layer 2, addressing the growing demand for precise data in blockchain applications. ### Reliable Data Transmission The APRO Data Push model employs multiple high-quality data transmission methods, leveraging a hybrid node architecture, multi-centralized communication networks, the TVWAP price discovery mechanism, and a self-managed multi-signature framework. This ensures the delivery of accurate, tamper-resistant data, safeguarded against vulnerabilities or oracle-based attacks, ensuring reliability across diverse use cases. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
